Every internet search or ChatGPT query has an invisible cost, namely its environmental footprint. And yet assessing this impact remains complicated because of the lack of harmonised standards. The Altimpact project, led by the CNRS, the Ademe and the Inria is working on this challenge.

Check out #17 to help unravel one of the central mysteries in immunology: how, starting from a single bond between a receptor and an antigen, T cells can activate the whole cell and eventually the whole organism?

Point of no return: academic #funding is at a tipping point. When the effort and money spent applying for grants equals or exceeds the funding awarded, the system stops serving science and starts draining it. Time to rethink how we fund #research. 🧪🌐🌍 www.nature.com/articles/d41...

Point of no returns: researchers are crossing a threshold in the fight for funding
With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

Why would anyone want to be a scientist? Check out our new Essay from Martin Schwartz: journals.biologists.com/jcs/article/...
Screenshot of Essay from Martin Schwartz on 'Why would anyone want to be a scientist'. An anniversary article from The Company of Biologists published in Journal of Cell Science.

The first few lines are: It is difficult to fathom why anyone intelligent enough to be a scientist would actually choose to be one. Doing good science requires the utmost exertion of body, mind and spirit, yet is consistently filled with failure and rejection. But, strange even to myself, I not only don't question the unfavorable risk-to-reward ratio but consider myself astonishingly lucky to be a scientist. There are three fundamental pleasures that have sustained me through 50 years of this madness.
